The Research Of Greenhouse Remote Monitoring System Based On B/S

Greenhouse is an important part of the facility agriculture in our country. Greenhouse environment and crop production are closely related, and the environment is the basic guarantee to realize the automation and scientific management of the greenhouse production management. In recent years, the intelligent greenhouse industry in China developed rapidly, which benefits from the advanced automation equipment, as well as the rapid development of the Internet technology. The combination of these two technologies is the new technology areas - the internet of things, it is the future development of intelligent greenhouse industry in the new direction.Therefore, a remote greenhouse monitoring system based on B/S mode is designed in this paper.In this paper, firstly, the application background and research significance of B/S mode remote monitoring system are described. Combined with the greenhouse monitoring requirements, the overall structure of the system is designed, which mainly include the environmental parameters of wireless sensor network acquisition system, host computer,Web server and database server. According to the requirement of system hardware design,the wireless sensor network based on ZigBee protocol is built with SCM, wireless module and sensor, and the environment information is transmitted to the host computer. The monitoring system of the host computer is based on LabVIEW, which realizes user management, data analysis, control output and so on. By comparing the two models of B/S and C/S, the traditional B/S architecture of the business logic layer is extended, add the site monitoring layer, a design model of the four layer architecture model based on the B/S is proposed. The system uses PHP+Apache+MySQL development mode, has good portability.According to the system needs to build a table in MySQL, complete the storage of environmental parameters, user information and other relevant information. Through the analysis and research of Web network technology, PHP technology, Ajax technology and database technology, implements the Web Website front page and back page. Through the analysis of the front page and the background management of each function module realization process, it realizes the environmental data query, curve analysis, user login and disease information query and other functions. Through the system function test, the function of "field collection - remote monitoring" is realized.This system realizes the effective management of environmental information in distributed greenhouse and remote monitoring, not only has good real-time monitoring,openness and compatibility, but also online monitoring environment directly, provide scientific and reliable support for the user analysis.
